Debris Flow Probability

Debris Flows
Debris Flow Prediction
Debris flows are rivers of rock, earth, and other debris saturated with water. They develop when water rapidly accumulates in the ground during heavy rainfall or rapid snowmelt, changing the earth into a flowing river of debris. They flow rapidly, striking with little or no warning at avalanche speeds. They also can travel several miles from their source, growing in size as they pick up trees, boulders, cars, and other materials.

ArcGIS Geostatistical Analyst can help predict areas most susceptible to debris flows. Using sophisticated statistical methods, ArcGIS Geostatistical Analyst allows you to create a surface from data measurements occurring over an area where collecting information for every possible location would be impossible. You can predict and model spatial phenomena based on statistics and incorporate powerful exploration tools.
